Adaptive Decorrelation
In a movie theater, a large number of surround speakers
help create an enveloping surround sound experience.
If a home theater only has two sidewall surround
speakers, the surround speakers may sound similar to
headphones lacking spaciousness and envelopment.
Surround sounds will also collapse toward the closet
speaker as you move away from the middle seating
position. Adaptive Decorrelation slightly changes one
surround channel’s time and phase relationship with
respect to the other surround experience as in a movie
theater using only two speakers.
ASA (Advanced Speaker Array)
ASA is a proprietary THX technology which processes
the audio on the two side and two back surround
speakers for the optional surround sound experience.
When you set up your home theater system using eight
speaker outputs (Left, Center, Right, Surround Right,
Surround Back Right, Surround Back Left, Surround
Left, and Subwoofer), be sure to go to the THX Audio
Setup screen and choose the setting that closely
corresponds to the back speaker spacing. This will
reoptimize the surround sound field. ASA is used in
three modes: THX Select2 Cinema, THX Select2 Music
and THX Select2 Games.
Checking the Input Format
You can check the audio format of the input signals. While
audio from the player is being input, press DISPLAY on the
remote controller several times to switch the information
shown on the main unit display. If "Dolby D 5.1" is displayed
in Signal format, the Dolby Digital 5.1 ch signals are being
input.

The number of channels is not displayed when the input
signal format is "Dolby Atmos".
